Days after a second-grade teacher was found murdered in her home in Revere, Mass., a state police chief says an investigation has "led to one person and one person only, and he is now under arrest." Andrew MacCormack was arrested Tuesday and charged with murder in the death of his wife of two years, Vanessa MacCormack, reports MassLive. Andrew MacCormack, 29, had called 911 Saturday shortly before authorities found 30-year-old Vanessa badly beaten in the couple's home. The Office of the Chief Medical Examiner revealed she'd suffered blunt force trauma to the head, sharp force injuries to the neck, and asphyxiation, while "evidence suggested that the killer made concerted efforts to clean up the crime scene and dispose of related items."
A neighbor who encountered MacCormack Saturday says he "was shaking, crying, saying, 'What am I going to do without her? I can't believe somebody … did this to her,'" per the Boston Globe. MacCormack—who studied criminal justice in college, per People—was also seen breaking down at the home on Sunday, reports WBZ. Yet footage from private surveillance systems and public safety cameras pointed to him as a suspect, police say. "The evidence suggests that [Vanessa's] murder was a crime of domestic violence," says Suffolk County District Attorney Daniel F. Conley. According to her sister, Vanessa "loved her husband with every ounce of her soul" and was "the world's best mother" to the couple's 1-year-old daughter. "My heart is so broken that she is gone," she tells WCVB. (Read more murder stories.)
